Hi Guys,

Got myself into a dilema and some serious head scratching......

I've ended up with two lots of Rockshox SID's.

One 2009 with 100mm travel and QR.

One 2012 with 120mm travel with a 15mm Maxle.

Which would you use for XC Racing ???

If it helps, I'm 70kg, go fast on the flat and uphil and am more cautious downhill.

Thanks,

Pat.

    What bike? Do you have wheels that fit both? What has your weight or how you ride got to do with it?

    On one Whippet.

    Wheels fit either.

    Pressume light person would be able to set 120's on soft and get full travel.

    Depends entirely on how you like the bike to feel. The 120mm fork will improve stability but possibly at the expense of some climbing ability.

    You should set up any fork to have the right amount of sag for your weight and you will get full travel when needed. Personally I would go for the 120mm forks for the stiffer front end provided by the Maxle but my guess would be the longer forks sit the bike up a little more and may give you more confidence on the downs. However, you don't win xc races on the downs so maybe lighter shorter forks would give you more benefits?

    The 100mm, lower front end, lighter, sorted for XC racing

    You may find you can swap the lowers putting the Maxle onto the 100mm forks, I understand you could if they were both 2009/10, not sure about a 2012 (not hard to find out by trial and error), but the 26" 100mm SID is pretty stiff so adding weight with the Maxle may not make you any faster

    Cheers.

    The consensus seems to be 100mm with Maxle.

    I'm pretty sure the 120's can be limited to 100 mm travel.

    The 2012 I believe can't, it needs a new air shaft. Plus it would still have the longer uppers I believe that are part of the 120mm and weigh more.

    My 2012 dual air would only need spacers fitted not a new air shaft.

    2012 won't need a new air shaft.

    Sorry, its the later solo that does, that aside, it still weighs more and for XC racing that's the wrong way to go.
